In SFU created a smart materials with nanostructure


Young scientists of Institute of Physics, Southern Federal University (SFU) have developed a technology of multi-component material systems, varying elements of which may be obtained nano-structured materials for specific industrial purposes, the university said in a statement.

Work in this direction led to the Institute of Physics in 2005. Multifunctional materials, created for environmentally sound technologies can be used in aircraft, rocket, radio engineering (inspection), information and communications industry, medical diagnostics and spintronics.

Earlier in the industry used piezoelectric material PZT-19 (lead zirconate titonat), representing a two-component system. SFU Researchers have established systems, which may include a third and a fourth dimension. Importantly, it will piezoelectric ceramics (man-made material with certain physical attributes) lead-free, which, along with three other heavy metals — cadmium, mercury and hexavalent chromium — the European Union banned since 2006 for use in industry.

"The number of components increases at times, there can be a different composition, and different proportions of ingredients. One production line (one circuit, one officer and one reagent) with different composition of components replaces several lines. The new technology also allows you to "adjust" the properties of the material under a particular purpose or engineer, to create a device based on it, that is, to maximize the efficiency of the material, " — Explained the features of the new technology of materials Andryushin Constantine, who participated in the study.


The development of young physicists under challenging title: "Creating electro (magneto) active multifunctional nanostructured materials and environmentally sound technologies for their preparation for aircraft and rocket engineering, radio engineering (inspection), information and communications industry, medical diagnostics, spintronics" won first place in the category " Best Innovative Project "at the Youth Innovation Convention Rostov region, which ended Oct. 21.


Another young scientist from the Institute of Physics Michael Talanov also won first place in a different category "Best Innovative Idea" by presenting the development, within the framework of which, based on these technologies is expected to receive multi-mode "smart" piezoelectric materials to create precision devices robotics and aerospace industries. In addition, the new material can be used for sensors, manipulators, condensers and receivers, starting with early warning of earthquakes and echolocation and ending with mobile phone cameras, says Talanov.

Components included in the material systems have power twice lower, and the effectiveness and time — higher than existing materials. Efficiency of new material reaches 70-98%. Their advantages include developers and small size vehicles made on their basis. For example, most compact size pezomotor has just two millimeters, such small motors do not exist.

Now the main task for the Institute of Physics — to find an investor willing to invest in new technology, the report said. The possibility of mass production on the basis of their content Rostov scientists based on the fact that their ceramics have a much lower cost and better processability compared to peers — single crystals.
